3 balls\u003c\/h3\u003e\u003cp\u003eBalls are rated by their grade. A Grade 3 ball means that the ball is 3\/1,000,000” tolerance of sphericity, and so is extremely round. In fact, the races of any bearing can't come close to this level of precision in their trueness, but every component being closer to perfect helps decrease friction. Another feature of Grade 3 is surface finish, which in this case is free of scratches or scuffs, and to a \u0026lt;0.003 micron fine finish. The lower the grade number, the better is the ball. SLR uses only highest grade ceramic balls.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003eSilicon Nitride Balls\u003c\/h3\u003e\u003cp\u003eMade from pure Silicon Nitride material (Si3N4) with extreme high density from uniform compaction (3.25 g\/cm3), the micro-structural elements of this material is second to none. In other words, it is extremely dense. There are several materials used for ceramic balls and races and SLR only uses the best, Silicon Nitride. Other ceramic materials should not be considered because of their inferior characteristics. The high precision Grade 3, Si3N4 pure ceramic balls are 3\/1,000,000” from exactly round in sphericity. 60% lighter weight and 7 times harder than steel, friction is reduced to near zero. Resistance to heat is 8 times greater than that of steel, tougher and less brittle than other ceramic materials.
